The Drive did not say whether Shell will start accepting other popular QR Code based solutions like Alipay and Walmart Pay at its stations. Chase needs to justify the $100 million it invested in mobile-wallet technology, the Drive reported. Unfortunately the Drive did not say what Shell stations will accept Chase Pay.

Walmart Pay users will not get cash back by paying with Chase Freedom, but they can get 5% Cashback by using Chase Pay at Walmart. Walmart (NYSE: WMT), America’s retailer accepts Chase Pay because it is a quick-read (QR) code based application like Walmart Pay. Although Chase Pay users can get 10% cash back at Walmart; if they pay with the Chase Sapphire or Freedom Unlimited Cards, before December 24, 2017, Nerdwallet reported.

Like Apple Pay, Android Pay still has not cracked the hardest barrier of all big U.S. retailers.

Almost no major U.S. retail brands appear in the Where to Use Android Pay page at the app’s website. Such behemoths as Walmart, Amazon, Kroger, Home Depot, Lowes, CVS, Burger King, Safeway, and Target are conspicuously absent from the list. The same sorry situation is repeated at Apple Pay, where almost all the big names in U.S. retail are conspicuously absent.

It is possible for hackers to steal the Apple Pay “payment token” using public Wi-Fi or a fake Wi-Fi hotspot that asks users to create a profile. In other they can crack Apple Pay by using a time tested hacking tactic called Wardriving.

Chase apparently plans to fold Current C into its digital wallet Chase Pay, Business Insider reported. Chase Pay is accepted only at Starbucks and Best Buy right now, but Walmart has plans to start taking it sometime this year. That will give Chase an advantage over Apple Pay and Android Pay, which Walmart refuses to take.

So far you can only access Visa (NYSE: V) and MasterCard (MA) through Microsoft Wallet. American Express and Discover are not mentioned at its website. Just eight banks are mentioned but only two major US banks accept it; Bank of America and US Bank. One major Canadian Bank TD Bank is also mentioned at the website. Chase is listed there as coming soon

There are also plans to roll out Chase Pay at Walmart, Phillips 66 gas stations, Conoco filling stations, Shoprite and The Fresh Grocer supermarkets and Shell convenience stores within the next year or so. Chase and Walmart made a big deal of the availability through Walmart Pay a while back so that is probably a done deal.

If Walmart can roll out the world’s first blockchain-based inventory system it would be able to greatly reduce costs. That would make the company more efficient and ease the integration of online retail and brick and mortar stores.
